I do not know if the button in your installation works, but the screenshot is OK.

The factions in the russian civil war scenarios are the reds and two whites, if you are playing with the communist of course you must load RED, if not the white faction you play western (WHI) or eastern whites (WH3).

Normally the second button in the right would show/hide the factions played by the AI.

Well, if you want to avoid the shorter scenarios, I would go directly for the Grand Campaign, sure you will learn a lot of history. Do not forget to take a look at the documentation included in the game.
